Conventionally, traffic information on roads, especially on highways where the risk of accidents due to unexpected situations is high, traffic conditions and unexpected situations were announced through electric signs that were formed only at specific locations, so unexpected situations on the road were quickly notified to nearby drivers. There were limits to informing the public. In addition, recently, technology has been developed to display traffic information on all sections of the road using street lights that are essential on the road, but in most cases, unexpected situations are checked and reported through videos at a separate traffic control center. Since notification is made through streetlights, there is a time lag in providing information, which prevents immediate response to unexpected situations. The accuracy is low, and all unexpected situations on the road are not promptly notified.

The failure determination module 126 is configured to determine a failure according to the maintenance time of the vehicle 5 in the stationary state. If the maintenance time according to the average speed of the surrounding vehicles 5 is exceeded, the failure of the vehicle 5 is determined. Let's do it. For this purpose, the failure determination module 126 sets and stores information in advance about the maintenance time of the stationary state judged to be a failure according to the average speed of the surrounding vehicles 5, and the faster the average speed, the longer the maintenance is judged to be a failure. You can set the time to be short. Therefore, the failure determination module 126 prevents the stopping of the vehicle 5 due to congestion from being mistaken for a failure, and recognizes and notifies the failure faster as the speed of the surrounding vehicle 5 increases, thereby reducing the risk of failure. Effectively prevent accidents involving rear vehicles.

The failure information transmission module 127 is configured to transmit the failure information of the vehicle 5 to the streetlight 3, and transmits the failure information to the streetlight 3 existing within a certain range behind the vehicle 5 in which the failure occurred. It can be transmitted, and the transmitted streetlight 3 wirelessly transmits fault information about vehicles 5 passing through the streetlight 3, such as accident information.

The congestion detection unit 13 is configured to detect congestion of vehicles 5 on the road, and detects congestion according to the speed at which vehicles 5 pass through each section of the road. The congestion detection unit 13 can set a section by grouping a plurality of street lights 3 into one group, and calculates the average value of the speed of the vehicle 5 passing through each section at regular time intervals to determine the section accordingly. The level of congestion can be detected. In addition, the congestion detection unit 13 compares the degree of congestion between each section to recognize the section where sudden congestion occurs and informs the rear of this to prevent accidents due to sudden congestion. For this purpose, the congestion detection unit 13 includes a speed information reception module 131, an average calculation module 132, a speed information refinement module 133, an average correction module 134, a congestion information provision module 135, and congestion information.

It is judged to be an emergency and this is notified by streetlights (3). The sudden congestion warning module 137 notifies the sudden congestion by transmitting information of the sudden congestion to the streetlights 3 located in a certain range behind the section where the sudden congestion occurs, and the streetlights 3 are activated according to the sudden congestion. It can be made to blink, and the streetlight (3) wirelessly transmits information on sudden traffic congestion, such as accidents or breakdowns, to vehicles (5) passing nearby.

The detection and inspection unit 14 is a component that checks whether the congestion detection unit 13 is operating properly, based on the difference between the average speed calculated by the congestion detection unit 13 and the average speed of the actual vehicle 5. Make sure to check whether the finishing operation is working. In other words, the congestion detection unit 13 calculates the average speed at regular time intervals, and the detection and inspection unit 14 determines the average speed of the vehicle 5 passing through the corresponding section in the next time interval after calculating the average speed. By making a comparison with , you can check whether the average speed is being measured accurately. However, since the average speed between time intervals may occur naturally due to the occurrence of congestion, etc., the detection and inspection unit 14 detects the congestion detection unit 13 only when a large difference in average speed occurs repeatedly or occurs continuously. It is possible to improve the accuracy of inspection by judging it as a malfunction. In addition, the detection and inspection unit 14 detects not only when a large difference in average speed occurs, but also when it continues within the boundary range or less even if it is not large enough to cause a failure, and notifies the need for inspection. Preemptive action can be taken not only when an abnormality occurs but also when there is a risk of abnormality. To this end, the detection and inspection unit 14 may include a failure determination unit 141 and a danger warning unit 142.

The failure determination unit 141 is a component that diagnoses a failure of the congestion detection unit 13, and calculates the ratio of the difference by comparing the average speed according to the time interval for each section. And, if the ratio of the difference exceeds the standard value, the frequency is calculated at regular time intervals, and if the frequency exceeds the set value and occurs cumulatively, it is determined that the congestion detection unit 13 is malfunctioning.
